What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What does it mean for y to be a function of x?

Back

For y to be a function of x, each input x must correspond to exactly one output y.

Front

What is the slope of the line represented by the equation y = 2x + 3?

Back

The slope of the line is 2.

Front

What is the y-intercept of the line represented by the equation y = -x + 4?

Back

The y-intercept of the line is 4.

Front

How do you determine if an equation is proportional?

Back

An equation is proportional if it can be written in the form y = kx, where k is a constant.

Front

What is the difference between proportional and non-proportional relationships?

Back

Proportional relationships have a constant ratio between y and x, while non-proportional relationships do not.

Front

What is the value of x in the equation 3x + 5 = 11?

Back

x = 2.

Front

What does the graph of a non-function look like?

Back

A non-function graph may have multiple outputs for a single input, such as a vertical line.

Front

What is the equation of a line with a slope of -1 and a y-intercept of 2?

Back

The equation is y = -x + 2.

Front

How can you identify a function from a set of ordered pairs?

Back

A set of ordered pairs is a function if no two pairs have the same first element.
